Abstract
The utility model discloses a kind of keyword unlocking type transparent transmission earphone, including noise reduction microphone, noise analysis identification and transmitting device, particular keywords and special sound wave memorizer, audio switching circuit, loudspeaker, control signal transmission and feedback link, audio frequency control button, it is characterised in that：Noise reduction microphone monitors external sound, it is transferred to noise analysis identification and transmitting device, content with being stored in particular keywords and special sound wave memorizer compares, if comparison value is true, control signal is then sent to audio switching circuit, audio input is disconnected, and the external sound that noise reduction microphone is listened to is transferred to loudspeaker, user can hear extraneous incoming sound.User produces control signal to audio switching circuit again by audio frequency control button press, recovers audio input to loudspeaker.
Description
Technical field
A kind of earphone is the utility model is related to, especially a kind of Intelligent noise reduction earphone.
Background technology
Existing earphone often has a decrease of noise functions, shields external sound substantially during use.Such a design ignores external sound
Middle information that may be useful to earphone user.Other people can be can't hear often in the earphone using such a design to exhale user
Call out, or the useful information such as broadcast of public transport arrival of subway.
Utility model content
In order to overcome be not added with distinguishing in existing earphone noise reduction schemes to shield ambient noise, cause user timely
Obtain it is extraneous in relevant with user information the problem of, the utility model increase in earphone external sound monitor with
The device of identification, when recognizing the pre-set some keywords or characteristic voice of user, noise reduction is automatically stopped, is stopped automatically
Only in earphone audio broadcasting, and the keyword listened to and follow-up external sound are transmitted into the ear thoroughly.Until user operates ear
Machine associated button recovers broadcasting and the decrease of noise functions of sound, and now earphone noise reduction microphone is again introduced into listening state.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
1. noise reduction microphone in figure, the identification of 2. noise analyses and transmitting device, 3. particular keywords and special sound waveform
Memory, 4. loudspeakers, 5. audio switching circuits, the transmission of 6. control signals and feedback link, 7. audio frequency control buttons.
Embodiment
【Embodiment 1】
Earphone is internally provided with noise reduction microphone 1, and earphone is internally provided with noise analysis identification device 2.Noise reduction microphone
1 monitoring external sound is simultaneously transferred to noise analysis identification device 2, noise analysis identification device 2 by the sound received with it is specific
The audio stored in keyword and special sound wave memorizer 3 is compared, if compare successfully, send control signal to
Audio switching circuit 5, audio switching circuit 5 close audio input according to control signal and connect external sound, and user is now
Directly hear external sound.User presses the input that audio frequency control button 7 recovers audio.
